    The benefits of patented longevity protein™
    Designed for strength and longevity

    Supports muscle without spiking IGF-1, a pro-aging pathway.
    Uncompromisingly clean

    Vegan, free of soy, gluten, dairy, GMOs, added sugars, artificial sweeteners, or silica.
    Smart nutrition

    High in fiber and iron, and designed to support healthy blood sugar levels.
    Complete plant protein

    Vegan protein that rivals animal protein without the pro-aging downsides.

    Is your protein aging you?
    You're eating protein to be healthy—it's the fuel, and building block, of your body. But many protein formulations spike pro-aging pathways like IGF-1, and they're packed with hidden sugars and other additives that can compromise your health.  

    Prolon longevity proteins are the world's first precision nutrition formulations developed at the Longevity Institute of the University of Southern California and IFOM research center in Italy to support muscle without spiking pro-aging factors in the body.
